Does anyone know what file extension or format OS 10.5 DVD comes with? In other words, when you buy the "retail" version of OS 10.1 or 2 or any future editions, does the DVD come as a DMG format or ISO? It would have to come with either format so the Mac can boot off of the DVD.

Basically, what I am trying to do is make a bootable OS 10.5 DVD so I can install 10.5 on my Mac.

Any suggestions?
 
It does not come as .iso or .dmg, it comes as a data DVD. An .iso or .dmg file is only an image of a file (or packages of files).

Do you have downloaded an .iso or .dmg file and are unsure what it is?
 
No, I know what .dmg or .iso files are. I wasn't sure how the retail DVD's come as a format. So, the retail OS 10.x come as a bootable DATA DVD.

I downloaded the OS 10.5 retail file which comes as a .dmg file. Next, I took the .dmg file and expanded it so I can convert it to .iso format. That is where I am puzzled. I could take Nero 9 and create a DATA DVD with this file but I want it to be bootable so when I put the DVD into Mac then I can install 10.5 from DVD. I don't want any errors on the DVD.

So, do I have the procedure right with using Nero 9 to create the bootable DVD?
